- stops of window casings. To this end a fastening means has beendevised which comprises a member adapted to be conveniently attached tothe innermface of the screen frame and having a part designed to besecurely engaged with the inner face of the blind stop.

It is a further object to provide a con struction which will be readilyadjustable to different widths of blind stop members ofthe windowframes. It is also an object to devise a fastening means which will benot only strong and eflicient for the desired purpose, but also comprisea construction of but few parts which will be easy to manipulate andinexpensive to manufacture.

WVith these objects in view,:the invention will now be described withreference to the accompanying drawing, showing forms of constructionwhich have been devised for embodying the improvements, after whichthose features and combinations deemed to be novel will be severally setforth and defined in'the appended claims.

In the drawing Figure 1 is a sectional perspective view illustrating oneform of embodiment of the fastening means; 1

Figs. 2 and 3 are horizontal and vertical sectional views, respectively,of the same;

Fig. 4 is an elevation of a modified form;

Figs. 5 and 6 are sections taken on the lines V-V and VIVI,respectively, of Fig. 4:;

Fig. 7 is an elevation of a still further modified form; and

Fig. 8 is a section taken on the line VIII-VIII of Fig. 7.

Referring to the drawing in detail, and more particularly to Figs. 1 to3, these illustrate a portion of a window framework formed with theusual sash runways 2 and 4 separated by the parting stop or bead 6,

the outer wall of the outer sash runway a being formed by the blind stopmember 8. The screen frame 10 is designed to be clamped in positionagainst the outer face of this blind stop 8, and for this purpose I havedevised a fastening means to be carried by the screen frame and adaptedto retain the same in said position by engaging the inner face of saidblind stop 8. As shownin Figs. 1 to 3, this fastening means comprises abracket portion 12 of approximately U form, provided with a bolt 1d forsecuring the same to the screen frame, and having a turn button 16swivelly mounted on the inner end of the bolt, whereby the button may beswung into the runway ei into engagement with the inner face of theblind stop 8. The inner threaded end of the bolt 14: is equipped with anut 18 for holding the parts, when adjusted, in proper clampingrelation. The bracket 12 projects inward a distance substantially equalto the width of the blind stop, and its bolt opening 20, as well as thebolt opening 22 of the button 16, are slightly elongated transversely sothat either the bracket or the button, or both, may be adjusted tocorrespond to the width of the particular blind stop with which thedevice is being used, and the bracket thus fitted snugly againsttheadjacent face of the blind stop and the button extended substantiallyacross the inner face of said stop.

The'particular form of the bracket is such as to afford a securemounting on the screen frame, extending transversely or across the grainof the latter. The legs of thebracket are arranged in somewhat divergingrelation, for facilitating the nesting of a number of the bracketstogether in compact form suitable for packing.

.In Figs. 4 t0 6 is shown a construction in which the bracket 12 isformed with a body portion of substantially the same shape as thebracket 12, but is also provided with vertically extending portions 24:adapted to be secured by means of screws 26 to the screen frame 10. Ashort bolt 14 and nut 18 are employed for mounting the button 16 whichis of the same form as in the preceding construction, the head of thebolt in this case, however, being shouldered against the inner face ofthe bracket.

Figs. 7 and 8 show a modification in which the bracket 28 is stampedsomewhat in Z form for adapting the body portion of the same to fit theangle between the screen frame and the blind stop, with the lip portion28 in engagement with the inner face of the blind stop as clearly shownin Fig. 8. In this construction the bolt 30 passes through the screenframe and through the transverse slot 32 of the bracket, whereby thebracket may be adjusted as in the first modification for slightlyvarying widths of blind stops. A nut 34 clamps the parts in adjustedposition, for holding the screen in place.

From the foregoing it will be apparent that a simple and efficientconstruction of fastening means has been devised for carrying out thedesired objects of the invention. The parts of the device may be easilyapplied and manipulated, and will not readily get out of order. Ametallic construction for all the parts is preferred, and the button 16and nut 18 may therefore be made sufiiciently thin to permit lowering ofthe upper sash (not shown) where there is some clearance or play of saidsash in the runway 4; or, the blind stop may be cut out slightly on itsinner face, if desired, as at 38 (Figs. 7 and 8), and the parts soproportioned as to bring the face of the lip 28 (or the button 16, asthe case may be) flush with the inner face of the blind stop andentirely out of the path of the sash, and thus allow entirely freemovement of the latter.

While the foregoing represents practical and efficient forms ofembodiment of the invention, the right is reserved to such formalchanges and modifications as may fairly fall within the scope of theappended claims.

Claims:

1. The combination with a window blind stop and screen frame adapted tobe mounted against the outer face of said stop, of a screen fasteningmember carried by the inner face of said frame and comprising. a portionprojecting inward toward the inner face of said stop and abuttingagainst the in termediate side face of the stop, and a portionprojecting at substantially right angles against the intermediate sideface of said stop, said member being mounted on said frame foradjustment in a direction toward and from said blind stop to accommodatevarying widths of blind stops, said member being provided with a portionprojecting horizontally in position to engage the inner face of saidstop for holding said screen frame in position.

3. The combination with a window blind stop and screen frame adapted tobe mounted against the outer faceof the stop, of fastening means carriedby the screen frame and comprising an element projecting inward towardthe inner face of said stop and abutting against the intermediate sideface of the stop, and a turn-button mounted adjustably for varyingwidths of blind stops, said button being adapted to swing intoengagement with the inner face of said stop for holding said screenframe in position.

4. The combination with awindow blind stop and screen frame adapted tobe mounted against the outer face of the stop, of a fastening devicecarried by said screen frame and comprising a bracket portion secured tothe inner face of said frame and shouldered against the intermediateside face of said stop, said bracket portion projecting toward the'innerface of said stop and substantially flush with said inner face of thestop, and a turn-button swivelly mounted on said bracket portion andadjustable to different widths of blind stops, said button being adaptedto swing into engagement with the inner face of said stop for holdingsaid screen frame in position. i
